The uppers of our shoes are a combination of genuine and vegan leather. Our inner soles are genuine suede and our signature flex-soles are comprised of 100% recyclable thermoplastic rubber (TPR). Our decision to collectively use genuine and vegan leather was a result of the rich textures and increased versatility that vegan leather offered to both our collections and our customers. We proudly hand-select both our leather and vegan leathers to ensure that it is the highest quality and condition. All of our materials are tested annually to ensure they are 100% safe and non-toxic.
